On my blog, I have a many-to-many relation between entries and categories, and in the sidebar of an entry I display the list of categories. For example: The entry at http://www.b-list.org/weblog/2007/dec/04/magic-tags/ belongs to one category, and so displays "It's part of the category Django." The entry at http://www.b-list.org/weblog/2007/feb/16/javascript-knowledge-gap/ is part of two categories, and so displays "It's part of the categories JavaScript and Programming." The entry at http://www.b-list.org/weblog/2007/jan/22/choosing-javascript-library/ is in three categories, and so displays "It's part of the categories Frameworks, JavaScript and Programming." The template snippet which does this is actually pretty simple: It’s part of the categor{{ object.categories.count|pluralize:"y,ies" }} {% for category in object.categories.all %}<a href="{{ category.get_absolute_url }}">{{ category.title }}</a>{% if forloop.last %}{% else %}{% ifequal forloop.revcounter0 1 %} and {% else %}, {% endifequal %} {% endif %}{% endfor %}. In short: 1. Pluralize "category" appropriately to "categories" when there's more than one category for the entry. 2. Loop through the categories. 3. Each time through, link to the category and show its title. 4. On the last trip through the loop, don't do anything special. 5. Otherwise, if it's the next-to-last time display a space followed by the word "and" followed by a space. 6. Otherwise, display a comma followed by a space. I don't like the serial comma (e.g., I prefer "Frameworks, JavaScript and Programming" to "Frameworks, JavaScript, and Programming"), but that'd be easy enough to do by changing step 5 to show "and," instead of "and". -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
